Infected ATMs gave away millions of dollars

What do you need in order to withdraw cash from an ATM? First, you need to have a debit or credit card, which acts as a key to your bank account. Second, you must know the PIN code associated with the card; otherwise, the bank wouldn’t approve the transaction. Finally, you need to have some money in your account that you can withdraw. However, hackers do things differently: they don’t need cards, PIN codes or bank accounts to get money. In reality, all they need is an ATM with some cash in it and a special piece of software.
